Abstract: Objective Investigating the variation of mosquito density with temperature,humidity and rainfall.Methods According to "the surveying project about the social health in the Three Gorges area"(modified in 2002),we collected datum of mosquito density and weather and made correlation and regression analysis between them by SPEM software.Results The correlation of temperature and mosquito density was positive,coefficient was 0.690 5(P< 0.05).Standard partial regression coefficients between mosquito density and temperature,humidity were respectively 0.851 7(P<0.05) and 0.382 1(P< 0.05),which is of statistic significance.Conclusion Temperature and humidity can influence mosquito density,especially temperature.
